Load Restoration

Load Restoration Analysis

The Load Restoration application minimizes the duration of an outage following a disturbance by automatically restoring power to the available portions of the system while maintaining fault isolation without exceeding the capacities of alternate power sources and routes.

Load Restoration Software Key Features

Restart Inhibition

Logical Load Sequencer

Load Restoration Priority

Intelligent Restoration

Operator notification and acknowledgement provides the means that allow the dispatcher to restart the loads. Armed with Switching Management, loads can be restarted step-by-step or in one action.

Where the restarting is determined to be invalid or unsafe, ETAP automatically inhibits the restart and provides the system operator with an indication that the load cannot be started.

Restoration qualification feature evaluates the ability to restore loads by monitoring and comparing the following parameters:

System frequency

Available spinning reserve

Starting voltages

Operating voltages

User-defined logic

Alternate source detection

System configuration status

Interlock & switching sequence logics

Minimize System Maintenance

A key feature of Intelligent Load Shedding is the ability to update and customize the load shedding logic without performing any ILS Controller re-programming. Changing load priorities, adding / removing loads from the system, and optimizing logic are some examples of actions that do not require reprogramming of the ILS Controller.
